IMPORTANT SAFETY INSTRUCTIONS
WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that
can cause injury and damage! Failure to comply with the following SAFETY instructions could result in serious
injury or death to the operator or other persons. The owner of the machine must understand these instructions
and must allow only persons who understand these instructions to operate machine. Each person operating
the machine must be of sound mind and body and must not be under the influence of any substance which
might impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your
dealer cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER,
McDonough, Georgia 30253. Phone: (1-800-935-2967).
PROTECTION FOR CHILDREN
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the machine and the mowing activity.
Never assume that children will remain where you last
saw them.
1. KEEP children out of the mowing area and under
the watchful care of a responsible adult.
2. DO NOT allow children in yard when machine is
operated (even with the blade OFF).
3. DO NOT allow children or other passengers to ride
on machine or on attachments (even with the
blade OFF). They may fall and be seriously
injured.
4. DO NOT allow pre-teenage children to operate
machine.
5. ALLOW only responsible adults & teenagers with
mature judgment under close adult supervision to
operate machine.
6. BE SURE the area is clear of others before
mowing and turn machine OFF if anyone enters
the area.
7. DO NOT mow in reverse unless absolutely
necessary. LOOK BEHIND and down for small
children before and when backing.
8. USE EXTRA CARE when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.
PROTECTION AGAINST TIPOVERS
Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra CAUTION. If
you cannot back up the slope or if you feel uneasy on
it, DO NOT mow it. Use extra care with grass catchers
or other attachments; these can change the stability
of the machine.
1. DO NOT operate machine on slopes exceeding 10
degrees (18% grade).
2. Exercise EXTREME CAUTION on slopes. Turn
blade OFF when traveling uphill. Use first speed
and avoid sudden or sharp turns.
3. DO NOT mow back and forth across face of
slopes. Mow up and down.
PROTECTION AGAINST TIPOVERS
(Continued From Previous Column)
4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blade OFF and back
slowly down the slope.
5. STAY ALERT for holes and other hidden hazards.
Tall grass can hide obstacles. Keep away from
ditches, washouts, culverts, fences and
protruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) away
from edge of ditches and other drop offs. The
mower could turn over if an edge caves in.
7. Always begin forward motion in the #1 (slow)
speed position.
8. Use weights in accordance with instructions with
grass catcher.
9. DO NOT put your foot on the ground to try to
stabilize the machine.
10. DO NOT mow on wet grass. Reduced traction
could cause sliding.
11. DO NOT mow under any condition where traction,
steering or stability is doubtful without first test
driving over the terrain with blade OFF.
12. Operator Protective Structures are available for
this machine through your local Snapper dealer.
PREPARATION
1. Read this manual, get to know where all controls
are located and practice how to use them before
starting for the first time, and at the beginning of
each season. Read and follow Warnings and
Instructions on engine and machine. Read and
follow operator’s manual and instructions
furnished with attachments.
2. Only mature, responsible persons shall operate
the machine and only after proper instruction.
3. Data indicates that operators age 60 and above,
are involved in a large percentage of mower-
related injuries. These operators should evaluate
their ability to operate the mower safely enough to
protect themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammable
and vapors are explosive. Use only an approved
fuel container. Never remove fuel cap or add fuel
with engine running. Add fuel outdoors only with
engine stopped and cool. Clean spilled fuel from
machine. DO NOT smoke.
5. Practice operation of machine with BLADE OFF to
learn controls and develop skills.

SECTION 2 - OPERATION & MAINTENANCE
INTRODUCTION
For operation & maintenance of the Out Front and Mid
Mount Z-Riders, refer to their respective operator’s
manuals. Operation of the MMZ/OFZ Grass Catcher is
an integral part of the blade operation of both Z-Riders.
WARNING
DO NOT operate machine without entire grass
catcher, deflector or guards in place.
2.1 GRASS CATCHER OPERATION
A. After the engine has been started; the grass
catcher blower will be activated when the blade
switch is pulled “OUT" See Figure 2.1.
FIGURE 2.1
B. When mowing, grass is discharged into the
cannister at the rear of the mower. As the grass
enters the cannister, it causes the indicator located
on the top cover to spin. When the indicator slows,
or stops, the cannister should be emptied. See
Figure 2.2.
FIGURE 2.2
WARNING
DO NOT turn around to inspect indicator when
mowing. STOP the machine, place the joystick in
Neutral (N) and engage the Parking Brake Lever. Then
turn to see if indicator is in motion or stopped.
2.2 EMPTYING GRASS CANNISTER
A. Stop blades. Push blade switch “IN”.
B. Stop engine by turning key to the “OFF” position.
C. Apply parking brake.
D. Remove “S” hook (bungee) from hole in top
cover.
E. Raise top cover until it latches in the “UP”
position. Latch engages automatically when cover
is lifted.
F. Remove the grass cannister.
G. Dispose of grass trimmings according to local,
state & Environmental Protection Agency codes
and regulations.
H. Reinstall grass cannister in reverse order.
I. Manually remove latch. First lift container top
cover removing weight off of latch. Raise latch while
at the same time lowering top cover. Secure cover
with bungee hook.
NOTE: When emptying grass container, check the
indicator mechanism under the top cover to insure
that it is operating correctly. Clean mechanism of
any debris buildup.
2.3 SIDE DISCHARGING WITH CATCHER INSTALLED
A. If you wish to “Side-Discharge” the grass
clippings for a short period with the catcher
installed, place discharge adapter in chute hanger
and secure with washer and hairpin. See Figure
2.3.
B. Install the discharge deflector previously
removed on the mower deck.

SECTION 2 - OPERATION & MAINTENANCE
2.3 SIDE DISCHARGING WITH CATCHER INSTALLED
C. If you wish to “Side Discharge” the clippings for
an extended period of time with the catcher in place
perform Steps A & B above and, also remove the
blower belt from the blower pulley and engine
pulley.
NOTE: The clutch drive belt removed in Step 1.1
should be reinstalled at this time.
2.4 CLEARING CLOGS FROM DISCHARGE CHUTE,
GRASS TUBES & BLOWER.
The grass catcher may become plugged with
clippings if grass conditions are too severe or the
machine is used improperly. If plugging occurs,
attempt the following:
1. Ground speed too fast - cut at slower speed.
2. Engine speed too slow - set engine speed control
to “FAST” position.
3. Removing too much grass - raise cutting height
and cut lawn more frequently.
4. Grass is too wet from dew or rain - allow grass to
dry.
5. Blades are too dull or worn - inspect blades and
replace as necessary. Use only genuine SNAPPER
replacement blades.
6. Incorrect blade(s) - catcher operation requires
high lift blade(s). Check to make sure proper blades
are installed. The 52” mower comes equipped with
high lift blades. The 61” mower requires the
installation of a high lift blade on the discharge
spindle only and comes as part of the kit.
7. Deck, deck adapter, blower or tubes have
clipping build up - clean all clippings from all
internal surfaces.
WARNING
DO NOT put fingers or hands inside fan! STOP
blades. STOP engine. Remove key. Use only a stick,
or other suitable means, to clear the fan of clogs or
other obstructions!
WARNING
DO NOT attempt any adjustments, maintenance or
repairs with engine running. STOP blades. STOP
engine. Remove key.
WARNING
Grass Catcher components are subject to
deterioration. Inspect frequently. Replace worn or
damaged components immediately. Use only genuine
SNAPPER replacement parts.
A. TO CLEAR A PLUGGED GRASS TUBE OR
DISCHARGE ADAPTER
1. Stop blades and blower. Stop engine. Remove
key.
2. After all rotating components (engine, blower,
blades) have come to a complete stop, remove
discharge adapter from deck.
3. Clear any obstructions from adapter and tube.
Use a stick to reach into the tube.
4. Install discharge adapter.
B. TO CLEAR A PLUGGED BLOWER
1. Stop blades and blower. Stop engine. Remove
key.
2. After all rotating components have come to a
complete stop, loosen the hose clamps at the inlet
and outlet of the blower.
3. Remove grass tubes from blower.
4. Using a stick or similar object, clear all
obstructions. DO NOT INSERT HAND.
5. Reinstall grass tubes to blower and securely
tighten hose clamps.
2.5 MAINTENANCE
Grass catcher components are subject to wear and
deterioration. All components must be inspected
frequently. Inspect the following before each use.
1. Grass Tubes. Check tubes for wear, tears and
holes. Replaced as needed.
2. Blades. Check blades for sharpness, wear,
flatness and damage. Refer to OFZ/MMZ
Operator’s Manual for blade wear limits and
sharpening/replacement instructions.
3. Blower. Check blower impeller, blower housing
and inlet/outlets for signs of wear and deterioration.
Replace as needed. Check all fasteners and
hardware to insure none are missing and all are
tightened securely.
4. Belts. Check belts for wear and fraying. Replace
as needed.
5. Idler Arm. Lubricate idler arm bushing with 1 to 3
shots of General Purpose grease from a grease
gun. Check idler arm to insure it pivots freely and
bushings are not worn. Replace worn bushings as
needed.
6. Gear Box. Right angle drive gear box requires
no maintenance. Inspect for signs of leakage. If
leakage is observed contact your local SNAPPER
Dealer for assistance.
